Granted: 1993-06-22
Abstract: ABSTRACT OF THE DISCLOSURE A separate refrigeration system in a conventional refrigerator  for dispensing  a chilled carbonated  liquid such as water or a beverage from the front door of the refrigerator and is comprised of a refrigerator having a freezer compartment wherein there is located a condenser. The   condenser   is   interconnected   with   a   combined evaporator-carbonator unit located in the front door.  The freezer compartment accordingly acts as a heat sink for the condenser.   The evaporator unit being integral with the carbonator,  operates to chill  the  carbonator.   When desirable, the condenser and evaporator can be replaced by a liquid heat transfer system having a heat absorbing coil assembly located in the carbonator and a heat dissipating coil assembly in the freezer compartment or by a constant temperature  heat  pipe  having  its  heat  dissipating  end located  in  the  freezer  compartment  while  its  heat absorbing end is located in the carbonator.

Abstract: This invention describes a wooden wall construction and method of making the same for a wooden building.  In particular, this invention provides for a wall construction which reduces the problem of gap formation between adjacent timber members caused by factors such as wood shrinkage and foundation movement.          Upright timber members are provided with vertical grooves aligned so as to receive extensions from the ends of stacked horizontal timber members of uniform length.  With the exception of the lower-most horizontal timber members, these members are not secured to the upright timber members so that they can move upwards or downwards within the grooves to accommodate shrinkage and settling factors.  Preferably when settling of the horizontal timber members has occurred to a significant extent, the roof structure will then rest on the upright members.

Title: Process for removing nox and sox from exhaust gas
Inventor: SKELLEY ARTHUR P
IPC: B01D53/34
Filed: 1992-08-28
Granted: 1999-11-30
Abstract: Exhaust gases containing oxides of nitrogen and sulfur from a fired process heater, a fossil fuel fired boiler, or a chemical process are diverted from a stack prior to admission to the atmosphere through a duct system containing heat exchangers that reduce the exhaust gas from an elevated temperature, if any, to about ambient temperature. Any heat extracted from the exhaust gas may be transferred to the boiler feed water which would serve to reduce the energy cost of operating a boiler.      Once the exhaust gas is cooled to about ambient temperature, the gas is then mixed with an oxidant, such as ozone, at a preselected molar ratio to transform the oxides to higher orders of nitrogen and sulfur oxides to increase the absorbability of the nitrogen and sulfur oxides in a reagent solution. The reagent absorbs the oxidized contaminants from the exhaust gas. The oxides are transformed to dilute acids which are then neutralized to form salts that are acceptable for discharge to a municipal waste water treatment plant. The treated exhaust gas is then emitted from an exhaust stack containing contaminants at a level meeting air quality standards. Additionally any heat recovered from the exhaust gas can be used to lower operating costs.

Title: Electronic circuit breaker with protection against sputtering arc faults and ground faults
Inventor: MACKENZIE RAYMOND WARREN
IPC: H02H3/44
Filed: 1992-09-25
Granted: 2003-03-18
Abstract: A circuit breaker bandwidth limits a sensed rate of change of current, di/dt, in the neutral conductor of a protected electrical system and fullwave rectifies the. bandwidth limited di/dt signal for comparison with an instantaneous trip reference signal. The bandwidth is selected to provide a selected relative sensitivity of the instantaneous trip to sinusoidal currents associated with overcurrent faults and step currents associated with sputtering arc faults. The rectified bandwidth limited di/dt signal is also filtered and delayed for comparison with a delayed trip reference signal. The time constant for the filter is selected to provide a selected relative sensitivity of the delayed trip to overcurrent faults and sputtering arc faults. A low mu sensing coil used to generate the di/dt signal can also serve as the neutral current sensing coil of a dormant oscillator ground fault protection system.
